He J., and Li J., 2025, Review of nutritional requirements in chickens: optimizing feed formulation for growth and health, Animal Molecular Breeding, 15(1): 29-38 (doi: 10.5376/amb.2025.15.0004)

Nutritional requirements of chickens have crucial roles in growth, health, and production performance. With the industry of poultry growing at a record-breaking pace, the goal of maximizing feed formulae for maximum feed efficiency, healthy development, reduced environmental pollution, and cost-saving has been among the research topics of concern. This review scientifically reviews the nutritional needs of chickens for essential nutrients, i.e., energy, protein and amino acids, minerals, vitamins, and water as well as differences in nutrition at various stages of growth. It also reviews how feed formulation can be improved, e.g., alternative sources of protein supplementation, precise balancing of amino acids, use of feed additives, and green feeding management. Nutrition not only affects growth rate but also plays a central role in immune response, gut integrity, and meat and egg quality. With ongoing developments in advanced farming technologies, precision feeding and data-driven feed optimization will play an increasingly central role in future research agendas. Studies on the genetics-nutrition interaction and the development of new feed ingredients will make poultry farming more sustainable. This book releases the latest data on poultry nutrition control, attempting to guide scientific feeding practices, enhance production efficiency, and achieve a maximum of animal health.
